The once beloved ES File Explorer was revealed recently to be little more than a Trojan Horse, used to get adware installed on thousands of devices with one update. This was apparently just the beginning. Users have started compiling a spreadsheet of apps that sneak the same adware-infused charging lock screen onto your device. There are already about 20 of them. Google, where are you?
Google needs to address this grotesque abuse of its users quickly and decisively, and remove all applications that install this adware from the Play Store, no questions asked. This is in direct violation of the Play Store rules.
